Chapter 1: Introduction
Recovery from AC Power Loss
The Basic I/O System (BIOS) provides a setting that determines how the system will respond
when AC power is lost and then restored to the system. You can choose for the system to
remain powered off (in which case you must press the power switch to turn it back on), or
for it to automatically return to the power-on state. See the Advanced BIOS Setup section
for this setting. The default setting is Last State.
1.4 System Health Monitoring
This section describes the health monitoring features of the X11SSZ-TLN4F/QF/F
motherboard. The motherboard has an onboard Baseboard Management Controller (BMC)
chip that supports system health monitoring. Once a voltage becomes unstable, a warning is
given or an error message is sent to the screen. The user can adjust the voltage thresholds
to dene the sensitivity of the voltage monitor.
Onboard Voltage Monitors
The onboard voltage monitor will continuously scan crucial voltage levels. Once a voltage
becomes unstable, it will give a warning or send an error message to the screen. Users can
adjust the voltage thresholds to dene the sensitivity of the voltage monitor. Real time readings
of these voltage levels are all displayed in BIOS.
Fan Status Monitor with Firmware Control
The system health monitor embedded in the BMC chip can check the RPM status of the
cooling fans. The CPU and chassis fans are controlled via lPMI.
Environmental Temperature Control
System Health sensors in the BMC monitor the temperatures and voltage settings of onboard
processors and the system in real time via the IPMI interface. Whenever the temperature of
the CPU or the system exceeds a user-dened threshold, system/CPU cooling fans will be
turned on to prevent the CPU or the system from overheating.
Note: To avoid possible system overheating, please be sure to provide adequate air-
ow to your system.
System Resource Alert
This feature is available when used with SuperDoctor 5
®
. SuperDoctor 5 is used to notify the
user of certain system events. For example, you can congure SuperDoctor 5 to provide you
with warnings when the system temperature, CPU temperatures, voltages and fan speeds
go beyond a predened range.
